Objective. The aim of this study was to determine the separate and combined contribution of gender, age and relationship status to the differences in attachment styles and aspects of sexuality (sexual self-esteem and sexual satisfaction). Methods. The sample included members of the general population (N=632). The following measures were used to examine attachment styles and aspects of sexuality: Modified Inventory of Experiences in Close Relationships, The Sexuality Scale and The New Sexual Satisfaction Scale. Results. Gender differences were established, indicating more pronounced anxious attachment and lower sexual self-esteem in women compared with men, regardless of relationship status. Age was negatively associated with sexual satisfaction. Single participants had higher levels of avoidant attachment especially in the youngest and the oldest age group. They also had lower sexual self-esteem and sexual satisfaction compared with coupled participants. Conclusion. Gender age and relationship status contributed individually and jointly to individual differences in attachment styles and sexual self-esteem.
